P32 and P3at trigger bars

Are they the same length?
Isn't the trigger bar for the P3at about 5/16" longer?
Or maybe the PF9's is the one 5/16" longer.
I received a trigger bar, from Keltec, that was that much longer than the bar for my P32 that I'd ordered.
They could not tell me which one they'd sent by mistake...but I intend modifying (shortening, drilling new hole) it 1/8" to shorten the trigger on my P32.
Will that work?...All you gunsmiths here.
